Tests:

  • toFixed(4) someFloat.toFixed(4); someFloat.t

     
    someFloat.toFixed(4);

  • toPrecision(4).toString()

     
    someFloat.toPrecision(4);

  • (Math.round(*10000)/10000).toString()

     
    (Math.round(someFloat*10000)/10000);

  • Math.floor fast

     
    ~~(someFloat * 10000) / 10000;

  • Math.trunc

     
    Math.trunc(someFloat * 10000) / 10000;

  • numeraljs

     
    numeral(someFloat).format('0.0000');
